In this fanfiction, it could be that Mufasa is brought back to life by some magical force. When he meets Simba, there is an initial shock and then pure joy. They then set out to restore the Pride Lands to an even greater glory. Mufasa shares his long - lost knowledge about the hidden parts of the Pride Lands, and together they form a stronger bond as father and son while working towards the betterment of their kingdom.
A new character could be introduced as the antagonist. For example, a powerful and greedy hyena who wants to take over the Pride Lands. When Mufasa and Simba meet, they have to team up to fight this new threat. The hyena might have some special powers or a large army of his own followers.
In some lemon fanfictions, their relationship might develop more quickly. For example, Simba could have a series of adventures where he discovers more about his father's past in a very short time. This new knowledge could make him idolize Mufasa even more and strive to be like him sooner.
One possible plot twist could be that Simba, instead of facing Scar alone in the final battle, teams up with an unexpected ally from the outskirts of the Pride Lands. Maybe a group of outcast animals who have their own reasons to oppose Scar's tyranny. This would change the whole dynamic of the classic story and add a new layer of complexity.
Well, perhaps Scar would initially be defensive when meeting Mufasa in the afterlife. But Mufasa, being the noble lion he was, might offer Scar a chance to redeem himself. This could lead to a transformation in Scar, where he starts to understand the error of his ways. It could also show how the power of forgiveness can exist even in the afterlife.
There could also be a plotline where there is some sort of danger threatening the Pride Lands. Kovu and Mufasa, despite their differences, team up to face this threat. Kovu brings his unique skills and knowledge from his pride, and Mufasa uses his wisdom and leadership. As they work together, they develop a mutual respect for each other that was not there before.
Well, it could be that Simba adopts Kovu to unite the two prides. Kovu might be a key to bringing peace between the prides that have been at odds. Simba could teach Kovu about leadership and kindness. Kovu, in turn, might have to prove himself to the other members of Simba's pride, facing challenges and making friends along the way.
One possible plot could be that a magical spell is cast on Simba by an envious rival. This rival, perhaps a forgotten outcast from the pride, sees Simba's position as king and decides to play a cruel trick. Simba suddenly finds himself in a baby's body, with all his adult knowledge but none of his physical strength. His friends and family are confused at first. Nala might be especially protective, like she was when Simba was a cub the first time. Simba has to figure out how to communicate his situation to Rafiki, the wise old mandrill, who then sets off on a journey to find a way to reverse the spell. All the while, Simba is learning new things about his kingdom and the animals in it from this new, baby - like perspective.
It could be that Mufasa is moody because he's having self - doubts. He might be worried that he won't be a good father when the cub arrives. Sarabi, being pregnant, is in a more positive state of mind and tries to boost his confidence. She could share stories of how she believes he'll be a great father, like how he's been a great leader to the pride, and fatherhood is just an extension of that leadership.
A possible plotline could be that they meet during a time of drought and have to work together to find water sources for both the Pridelands and the Outlands. Another is that they meet while chasing the same group of hyenas who are causing trouble in both territories.
One interesting story could be about their adventures as cubs that were not shown in the original movie. Maybe they discovered a secret part of the Pride Lands together.
